So my front tranny seal is going and when I replace it I'm just going to do a new torque converter at the same time. 2005 f150 5.4 So I was shopping around and some places list 2 different converters. One with straight spline ribs and one with angled splines. Has anyone replaced there's and had to find out which they needed or ran into the problem of buying the wrong one? Or is this just a mistake on the auto parts websites.

Thanks
Mike

 

Get a higher stall one so you can do a higher redline for more power if you want. Anything over 5400 rpm will baloon our beloved transmissions stock tq converter's. Its the weak point. Havent had to touch mine hopefully wont have too for a long time.
